Previously we haven't been doing anything with verbose BUG() reporting, and we've been relying on the oops path for handling BUG()'s, which is rather sub-optimal. This switches BUG handling to use a fixed trapa vector (#0x3e) where we construct a small bug frame post trapa instruction to get the context right. This also makes it trivial to wire up a DIE_BUG for the atomic die chain, which we couldn't really do before. Signed-off-by: NPaul Mundt <lethal@linux-sh.org>

The following moves the creation of IPR interupts into setup-7750.c and updates a few other things to make it all work after the "Drop CPU subtype IRQ headers" commit. It boots and runs fine on my titan board. - adds an ipr_idx to the ipr_data and uses a function in the subtype code to calculate the address of the IPR registers - adds a function to enable individual interrupt mode for externals in the subtype code and calls that from the titan board code instead of doing it directly. - I changed the shift in the ipr_data to be the actual # of bits to shift, instead of the numnber / 4 - made it easier to match with the manual.

Since all of the sys_timer sources currently do this on their own within the ->get_offset() path, it's more sensible to just have the caller take care of it when grabbing xtime_lock. Incidentally, this is more in line with what others (ie, ARM) are doing already. Signed-off-by: NPaul Mundt <lethal@linux-sh.org>

The end of the store queue bitmap is miscalculated when searching for a free range in sq_remap(), missing the PAGE_SHIFT shift that's done in sq_api_init().

This makes the early printk support somewhat more flexible, moving the port definition to a config option, and making the port initialization configurable for sh-ipl+g users. At the same time, this allows us to trivially wire up the SH7780 SCIF0, so that's thrown in too more or less for free. Signed-off-by: NPaul Mundt <lethal@linux-sh.org>

There were a number of places that made evil PAGE_SIZE == 4k assumptions that ended up breaking when trying to play with 8k and 64k page sizes, this fixes those up. The most significant change is the way we load THREAD_SIZE, previously this was done via: mov #(THREAD_SIZE >> 8), reg shll8 reg to avoid a memory access and allow the immediate load. With a 64k PAGE_SIZE, we're out of range for the immediate load size without resorting to special instructions available in later ISAs (movi20s and so on). The "workaround" for this is to bump up the shift to 10 and insert a shll2, which gives a bit more flexibility while still being much cheaper than a memory access.

The implementation of system call tracing in the kernel has a couple of ordering problems: - the validity of the system call number is checked before calling out to system call tracing code, and should be done after - the system call number used when tracing is the one the system call was invoked with, while the system call tracing code can legitimatly change the call number (for example strace permutes fork into clone) This patch fixes both of these problems, and also reoders the code slightly to make the direct path through the code the common case.

This drops the various IRQ headers that were floating around and primarily providing hardcoded IRQ definitions for the various CPU subtypes. This quickly got to be an unmaintainable mess, made even more evident by the subtle breakage introduced by the SH-2 and SH-2A changes. Now that subtypes are able to register IRQ maps directly, just rip all of the headers out. Signed-off-by: NPaul Mundt <lethal@linux-sh.org>

The conversion from IPR-IRQ to IRQ-chip resulted in the ipr data being allocated in a local variable in make_ipr_irq - breaking anything using IPR interrupts. This changes all of the callers of make_ipr_irq to allocate a static structure containing the IPR data which is then passed to make_ipr_irq. This removes the need for make_ipr_irq to allocate any additional space for the IPR information. Signed-off-by: NJamie Lenehan <lenehan@twibble.org> Signed-off-by: NPaul Mundt <lethal@linux-sh.org>

Currently the INTC2 code contains a fixed IRQ table that it iterates through to set the handler type, we move this in to the CPU subtype setup code instead and allow for submitting the table that way. This drops the ST40 tables, as nothing has been happening with those processors, while converting the only existing users to use the new table directly (SH7760 and SH7780).

With the recent change ripping out interrupt_table, explicit padding of the table was missing, causing bad things to happen when manually inserting handlers in to the table. This problem particularly showed up in relation to do_fpu_state_restore() which was inserted quite deeply in to the table and ended up scribbling over a slab object.
